Written by Pendell Meyers, edits by Smith Two patients presented with acute chest pain/pressure. Here are their ECGs: Patient 1: Patient 2: See below for "answers", and below that for both cases. "Answers": Patient 1 shows very subtle high lateral OMI, South African flag sign. She had an acute LAD OMI in the process of reperfusion, see case below. Patient 2 has a normal variant ECG which mimics high lateral OMI, and ruled out for MI, see case below.

UPDATE: The penalty phase of the Centers for Medicare & Medicaid Appropriate Use Criteria (AUC) program has been suspended until further notice.

Objectives Accurate prediction of heart failure (HF) patients at high risk of atrial fibrillation (AF) represents a potentially valuable tool to inform shared decision making. No validated prediction model for AF in HF is currently available. The objective was to develop clinical prediction models for 1-year risk of AF. Methods Using the Danish Heart Failure Registry, we conducted a nationwide registry-based cohort study of all incident HF patients diagnosed from 2008 to 2018 and without history
